Message elements

How the first alert is built

To check this alert, Claude (an AI) read it in full 25 separate times, independently. Each read decided whether the message answers each of the six questions and gave a short reason. A final reviewer then weighed all 25 and wrote the plain-English verdict you see when you open a row. The score (for example 22/25) is how many reads agreed; the 25 individual reads are tucked underneath if you want to check them.

  • Sourceabsent0/0

    Who is sending the alert and who is responding. People act faster on a message from a clearly identifiable, credible sender, such as a named department, the police, or a branded alert system, than on an anonymous notice. A branded signature counts.

  • Hazardabsent0/0

    What the threat actually is. A complete warning names the specific danger, such as a shooter, a fire, a tornado, or a gas leak, rather than a vague emergency, because people decide what to do based on what they are facing.

  • Locationabsent0/0

    Where the threat is. Saying whether danger is in a specific building, a part of campus, or area-wide lets people judge their own proximity and choose a safe direction. Without a where, a warning is hard to act on precisely.

  • Guidanceabsent0/0

    The protective action to take. A clear, specific instruction, such as shelter in place, evacuate, avoid the area, or run-hide-fight, drives faster and more correct protective behavior than describing the threat alone.

  • Timeabsent0/0

    When the message applies. A timestamp, the word now or immediately, or a phrase like until further notice tells the reader whether the danger is current and how quickly to act.

  • Impactabsent0/0

    What the hazard could do to the people in its path. Beyond naming the threat, a complete warning conveys its potential consequences or severity, such as that a tornado can level buildings or that a leak could be explosive, so recipients grasp how much danger they are in. Research on warning message content finds that a concrete impact statement helps people personalize their risk and act sooner.

About this analysis
Context

Background

Hurricane Helene struck the South Carolina Upstate on the night of September 26-27, 2024, bringing what The Tiger student newspaper called 'unprecedented' conditions to Clemson and the surrounding area. The university closed at 7:00 PM on September 26 ahead of the worst weather, which arrived overnight with wind gusts exceeding 50 mph and 8 to 10 inches of rainfall. While the main campus retained power and damage was described as minimal, the broader region suffered widespread power outages and downed trees blocking roads. The university adjusted Saturday gameday operations for the football game against Stanford, delaying parking lot openings and gate times, but faced public criticism for proceeding with the game while many surrounding residents remained without power. Classes were ultimately canceled through Monday as recovery continued.
